Rename "Get Tails" as "Install Tails"
Feedback from @groente also spotted during #18922 (closed).
Many people are confused not see an immediate download link when clicking on "Get Tails", perhaps "Install Tails" is a better term?
I think that I went for "Get Tails" because it's a pretty common practice, but indeed "Install Tails" might be better because it's the term that we are using everywhere else and "getting" Tails is not only about "downloading" it but is a more evolved process.
